REWRITABLE COLOR IMAGE RECORDING MEDIUM AND IMAGE FORMING METHOD USING THE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a thermosensitive recording medium which has full-color recording and rewritable characteristics made compatible with each other and an image forming method. SOLUTION: This rewritable color image recording medium provided with a thermosensitive layer containing a cholesteric liquid crystal compound which has <=2,000 molecular weight and >=35 deg.C glass transition temperature is provided between two substrates, at least one of which is transparent. An image is formed by varying the temperature of the rewritable color image recording medium from 1st temperature to 2nd temperature (the cholesteric liquid crystal compound forms a cholesteric liquid phase at least one of the 1st temperature and 2nd temperature) according to the desired image, and then fixed by rapidly cooling the recording medium so that the thermosensitive layer is cooled to the glass transition temperature or below.
